LOOSE-LEAF BINDER.

Application filed January 7, 15326;

This inventionlrelates to improvements in loose leaf binders and moreparticularly tothat type of loose leaf binder disclosed in my co-pendingapplication filed July 6, 1925,

5 Serial No. 41,78 and which binders are designed primarily for use byministers, professors, and others who desire or are required to have athand text or other matter of a permanent nature and memoranda or notesrelating; thereto. As in the said copending application, the presentinvention contemplates the provision of a binder especially designed toretain, in position for convenient reference, the text leaves of theBible, and auxiliary or memoranda leaves upon which memoranda and notesmay be written, and one of the primary objects of the present inventionis to so construct the binder that while independent binding:- orretaining units are provided. for the main or text leaves and theauxiliary or memoranda leaves, these units will be so constructed thatthe memoranda leaves, in any number, may be transferred to the main 2binder unit or units and the main or text leaves may be transferred tothe auxiliary binder unit,.so that, in deliveringa sermon, a ministeremploying the binder may readily refer to the Biblical text as well asto any 30 memoranda or notes which he has made upon one or more of theauxiliary leaves.

Another object of the invention is to so construct the main andauxiliary binder units that each unit will be capable of ad justment tosnugly and securely retain any desired number of leaves, withinreasonable limits, and in such a manner that when the binder is spreadopen, all of the memoranda leaves or what may be considered as temporaryleaves, may be disposed fiatwise so as to permit of more ready andconvenient consultation of the memoranda written thereon, theconstruction, furthermore, being such that when the binder is spreadopen, the two banks of permanent or text leaves will lie flat and nointerference will be oi'feredrto the turning of any of the leaves toenable the user to consult the particular portion of the text or anymemoranda writ ten upon the temporary leaves.

Another object of the invention is to so construct the binder thatregardless of the number of permanent and temporary leaves retainedthereby by the main and auxiliary binder units, respectively,theinargins of the leaves will all register whenthe binder SeriaLNo.79,869;

is closed, thus avoiding the unsightly appearance which would bepresented by nonregistering leaves.

Another object of the invention-is to provide novel means for lockingthe adjustable leaf-clamping sections of the mainv binder unit inpositions of adjustment and in such manner as to permit of release ofthe permanent leaves whereby any desired number of said leaves may beremoved from the respective units or replaced therein as occaslon mayrequire.

Another object of the invention is toHso construct the main andauxiliary binder units that said main units may be readily adjusted soas to accommodate between them an-ydesired number of temporary leavesand impart to the article as a whole the appearance of the compact book.

Another object of the invention is to pro vide an extremely simpleconstruction and arrangement of the component parts of the main andauxiliary binder units to per ,t of quick and ready adjustment of theunits independently as the use of the. binder may indicate.

Another object of the invention is to pro vi'de novel means for lockingthe binder in closed form and which means may be readily manipulatedfrom the lower endof the binder .to permit of spreading open of thehindr to flat and full open position.

Another object of the invention is to so construct the main andauxiliary binder units that the same will be exceptionally compact andbulging or distortion of the cover of: the binder will be avoided.

In the accompanying drawings:

Figure 1 is a plan view of the binder e1n-v bodying the invention,spread open, the temporary leaves being all arranged at one side of thebinder or, in other words, overlying one bank of the permanent leaves.

Figure 2 is a bottom edgeviewof the binder in spread open condition.

Figure 3 is a detail fragmentary view in elevation lookingv at the lowerend of the binder or, in other words, that end which is next adjacentthe-user, the binder being closed and the view-illustrating: in; fulland dotted lines the positions which will be assumedlby the lockingdevices upon the main binder units'W-hen the; units are substantiallyfilled and when they contain fewer leaves,

Figure l is a similanview lookingeat the upper end of the binder,

the binder units closed and the cover leaves spread open, the adjustablesection or" one of the main binder units being separated from the fixedsection thereof.

Figure 6 is a detail vertical transverse sectional view on the line 6-6of Figure 1, looking in the direction indicated by the arrows.

Figure 7 is a group perspective view illustrating parts of the binderlocated at the lower end thereof, disassembled.

Figure 8 is a similar view illustrating one end of the fixed andadjustable sections of one of the main binder units relatively displaced. 1

Figure 9 is'a vertical sectional view taken substantially on the line9-9 of Figure 5, looking in the direction indicated by the arrows Thebinder embodying the invention includes two cover leaves which areindicated by the numeral 1 and which leaves are of flexible leather orother material of a similar nature, and inside cover leaves 2 which maybe united in any suitable manner to the inner surfaces of the leaves 1and serve to somewhat stiilen the said leaves 1. The numeral 3indicatesthe back of the binder which is likewise of leather or anyother suitable flexible material and which has its marginal portions,indicated by the numeral 4, di posed against the inner marginal portions5 of the cover leaves 1, metal strips 6 being disposed against themarginal portions at of the said back'3, and a strip 7, likewise prelerably of leather, being disposed against the marginal portions 5 of thesaid cover leaves 1. Rivets 8 are secured through the said strips 6, thesaid marginal portions of the cover leaves and back, the strip 7 and aportion or the fixed sections of the main binder units.

Each of the main binder units comprises a fixed section indicated ingeneral by the numeral 9, and a removable and adjustable sectionindicated by the numeral 10. The fixed section 9 of each main binderunit is preferably formed from an integral sheet inetal blank andcomprises relatively right angularly disposed members 11' and 12, thelatter member being folded longitudinally, as at 13, so as to provide aportion 14; which occupies a plane diverging from the plane of themember 1 of which it constitutes a part, in the direction or" its freeedge, the said free edge of the member 1 1 being rolled to provide alongitudinal sleeve 15 which serves a purpose to be presently explained.Each end of the portion 14: of the member 12 is bent to extend at rightangles to the plane of the said portion 12, these ends being indicatedby the numeral 16, and the bends which are formed to provide the samebeing so located as to accommodate the end edges of the said member 12.In a like manner, the ends 17 of the member 11 are bent at right anglesto engage against the outer sides of the ends 16 oi the said member 12,and are folded over, as at 18, to provide portions 19 which engage theinner sides of the respective ends 16 of the said member 12. The foldedover portions '19 are each provided at its edge with a flange 20 formedwith a number of teeth indicated by the numeral 21, this flange extending at right angles outwardly from the plane of the said portion andbeing located substantially midway between the, fold 1S and the plane ofthe member 11. As will presently be explained, this toothed flange 20 ateach end of the section 9, constitutes a part of a locking means forholding the sections 9 and 10 assembled. A number of leaf-retainingposts 22 are secured and riveted at one end of the member 12 and theportion 14: thereof near the fold and are of a length equalsubstantially to the width of the member 11 of the said section 9, andthe permanent text leaves, which are indicated by the numeral 23, areprovided with perforations 24- near their inner margins, spaced tocorrespond with the spacing of the posts 22 so that a bank or stack ofthe leaves.

may be engaged with the posts and with their inner marginal portionsseating in the angle between the members 11 and 12 ot the fixed section9. The numeral 25 indicates small hinge rods which are fitted throughthe sleeves 15 of the fixed sections 9 and their ends, are secured inopenings 26 form 'L in end plates 27 which are disposed aga i the outersides of the end portions 17 of the member 11. The plates 27 are securedin place by 'means of screws 28 which are threaded through openings 29formed in the said plates 27 and openings 30 formed in the ends of thefixed section 9. The numeral 31 indicates a spacer having openingsformed therein which are designed to register with the openings 26 andwhich accommodate the ends of the hinge rods, the spacer 31 comprising aposed against the outer sides of substantially circular corner portionsof the plates 27, which portions are indicated by the numeral 33 and areprovided peripherally with teeth 34; which intermesh, the toothedperiphery of each of the portions 33 being concentric to the opening 26in the said por tion. overturned linger 35 which engages behind theother sides of the said portions 33 and serves to prevent separation ofthe spacer 31 from the toothed segments 33 and the hinge rods 25, itbeing understood that the said rods are securely held within the sleeve15 so as to provide against their longitudinal displacement. Tt will nowbe evident that the fixed sections of the main binder units areconnected for relative angular or swinging The spacer 31 is. providedwith an plate which is dis movement and that this movement is rendereduniform through the intermeshing of the teeth of segments 33.

Each of the QCljLTSlJzIlJlG and removable sections 10 of the main binderunits is, like the fixed sections 9, formed from a single sheet metalblank except for certain locking means to be presently described, andthe said section comprises relatively right angularly disposed members36 and 37, the member 37 being provided at each end with a pintle lug 38and the member 36 having each end bent up, as indicated by the numeral89, so as to provide a stop for a latch member which is indicated ingeneral by the numeral 40. The latch member d comprises a plate 41provided at one edge with spaced pintle lugs 4-2, and a wire spring 13is fitted throughthe pintle lugs 38 and -12 and has one end, indicatedby the numeral 4 1, engaged against the inner side of the member 87 andits othercnd, indicated by the numeral 45, engaged against the innerside of the latch plate 41, the latch plate being, in this manner,pivotally connected with the respective end of the member 37 andyieldably held in position resting against the respective stop 89, Thelatch plate 41 is provided at its free edge wit-h narrow flangeconstituting, in effect, a tooth 16, and it will be evident by referenceto Figure 5 ot'the drawings, that the section 1.0 is to be assembledwith the section 9 by i'lisposing the member 36 of the said section 10against the upper side of the member-11 oi the section '9 and thenbodily sliding the section 10 toward the member 12 of the said section9, the tooth 1 6 of the latch plate 41 riding over the teeth 21 of theflanges and engaging one or another or these teeth, depending upon thethickness of the bank of permanent leaves which are arranged upon theposts 22 oi the section 9, the member 37 of the section 10 beingprovided with similar posts, which are indi- ,cated by the numeral 7,and which engage in openings d8 formed in the marginal portions 01? thepermanent leaves 23. it will now be evident that the bank of permanentleaves is securely clamped at the inner margins off the leaves, betweenthe members 12 and 37 ot the sections 9 and 10 respectively, theprovision of a plurality of the teeth 21 upon each flange 20 providingfor looking 01"? the section 10 with its member 37 spaced from themember 12 of the section 9 varying distances corresponding to thethickness or the bank of leaves clamped between the sections. The latchplate 41 is provided at one edge with an outstanch ing lug l9, and acombined linger piece and detent is pivotally connected, as at 51, withan upstanding portion of the saidlug 49 and when elevated tothe positionshown in Figure 8 of the draw ngs,or the tit dotted line position shownin Figure 9, constitutes a finger Ji'ece against which pressure may beexerted in order to spring the respective latch plate 41 inwardly todisengage its tooth 46 from the teeth 21 of the respective flange 20,thus permitting of separation of the section 10 from the section 9. Whenthe linger piece or detent 50 is swung about its pivot to assume thedotted line position shown in Figure 8 and full line position shown inFigure 9, it will engage against the outer side oi the respective plate27 and, in this manner, the latch plate a1 will be securely held againstany accidental inward displacement which would eliect disengagen'ient ofits tooth from the teeth 21 of the respective flange 20.

It will be understood from the ioregoim that at the time of separationof either section 10 from the respective section 9, any one or more ofthe so-called pern'ianent leaves 23 may be removed or leaves which havepreviously been removed may be replaced.

Coact-i'ng locking means are provided at the lower and upper ends of thebinder for holding the main binder units in closedposition, as shown inFigures 3 and 4- or the drawings, and the means which is provided at thesaid low; end of the binder comprises a detent 52 which is disposedagainst the outer side of one of the plates 27 and is secured at one endby the respective screw 28, titted through opening 52 therein andthreaded into the opening 29 and is provided at its other end with aright angularly turned lug 58 which engages in a notch 54 formed in oneedge of the said plate 27. The detent- 52 is provided with anoutstanding flange 55 having a right angularly turned portion 56 whichspaced from the body oi the detent and formed with a pluralityof teeth-57. A latch member 58 is pivotally mounted upon the other plate 27 bymeans of rod 59 which. extends through an openil'ig 60 formed in theplate 27 and upon the end of which rod the said latch is secured, therod extending longitudinally between the members 12 and 14 of therespective fixed section 9. The latch member 58 is provided with a tooth6i and by reference to Figure 3 oil the drawings,

it will be observed that when the main binderunits are swung about thehingerods 25 in closing the binder, the tooth 61 of the latch memberwill ride over the teeth and have locking engagement with one or anotherof these teeth, depending upon the extent to which the binder is closed,and this depending in turn upon the thickness of the bank of memorandaor tem 'iorary binder leaves which are arranged between the banks ofpermanent binder leaves and which temporary leaves are indicated by thenumeral 62, the position of the parts when the latch tooth 61 is inengagement with one of the teeth 57 being shown in full lines in thesaid Figure 3, and when engaged with another one of the teeth 57, beingshown in dotted lines in the said figure.

In order to maintain the latch member 58 in position to coact with thekeeper member 52, wire spring 3 is l'xed at one end in an attachingmember 6 lsccured to the last mentioned plate 27 by means of therespective screw 28, fitted through an opening 64: in the said member 6%and threaded into an opening 27 in the said plate 27, and the other endof this spring is bent at right angles, as at 65, and engaged in anopening 66 formed in the said latch member 58. y

The locking means at the upper end of the binder is best illustrated, inFigure 4; of the drawings, and the same comprises a detent 67 secured toone of the upper pair of plates 27 by means of the respective screw 28and having an extension 68 provided with a plurality of teeth 69. Theend of the rod 59 which is opposite the end which carries the latch isfitted through an opening 7 0 formed in the other one of the upper onesof the plates 27 and is turned at right angles to provide a latch finger71, the end of which is turned laterally, as at 7 2, so as to coact withthe teeth 69. One edge portion of the last mentioned plate 27 isprovided with an arcuate portion 7 3 having shoulders or stops 74 and 75at the opposite ends thereof, and this edge portion is so located thatthe portion 72 of the latch finger will ride along the same, the fingerbeing normally substantially in engagement with the shoulder 74, andparticularly when the hinder is open as shown in Figure 6 of thedrawings. Inasmuch as the latch finger 71 and the latch member 58 arefixed with relation to the rod 59, it will be evident that by manuallyrocking the latch member 58 to disengage its tooth 61 from the teeth 57of the detent 52, rocking motion will be imparted to the said rod 59 andthe latch fir ger 71 will simultaneously be swung so as to be disengagedfrom the teeth 69 of the keeper or detent 67. Therefore, by simplepressure of the thumb against the latcl member 58, the binder may beinstantly spread open, it being understood that it is automaticallylocked when it is closed as shown in Figure l, this figure illustratingin full and dotted lines the dillerent positions assumed by the parts ofthe locking means when the binder contains a greater or less number ofmain and auxiliary binder leaves. 7

In order that the auxiliary leaves 62 may be retained in place, arcuateleaf-retaining hooks or members 76 are pivotally mounted each at one endas at 77, upon one of the hinge rods 25, and the other end of the hookmay be formed with a shallow notch 78 to coact with the other hinge rod25, the hooks being resilient so that when they are swung to occupy theposition shown in Figure 6 of the drawings, their free ends will rideover the last mentioned hinge rod and snap into engagement therewith.lVhen it is desired to remove any or all of the auxiliary leaves orsupply new leaves or replace those which have previously been removed,it may be accomplished by merely springing the hooks 76 upwardly, whenthe binder is open, and then disengaging or engaging the said leavestherewith, the said auxiliary leaves having openings 79 formed thereinto accommodate the hooks. The members let of the fixed section 9 of themain binder units are formed with slots 80 to accommodate the endportions of the auxiliary leaf retaining hooks 76 when the binder is inclosed position and by reference to Figures 8 and a of the drawings, itwill be observed that the said auxiliary leaves 62 have their innermarginal portions received between the sections 9 of the main binderunits when the binder is closed. I

In the structure disclosed in my co-pending application hereinbcforereferred to, the means for retaining the auxiliary leaves in place is soconstructed and located as to render it necessary to form the mainleaves or, in other words, the permanent text leaves, with notches intheir inner margins, but it will be observed that in the presentconstruction, this is not necessary, and inasmuch as all of thepermanent and temporary leaves are formed with the same number andarrangement of openings, the permanent leaves may be transferred to thetemporary binder units comprising the hooks 76, and any of the temporaryleaves may be transferred to the main binder units, so that, in thefirst instance, a portion of Biblical text may, for example, beassociated. with memoranda leaves, or memoranda leaves may beinterspersed with the text leaves.

It will likewise be evident that the auxiliary binder unit is adapted toaccommodate a greater or less number of auxiliary leaves, inasmuch asthe main binder unit constitutes, in effect, parts of the said auxiliaryunit, in conjunction with the hooks 76, in that they are adjustabletoward and from each other so as to more or less closely confine varyingnumbers'ot memoranda or temporary leaves which are disposed between themand engaged upon the said hooks.

It will be evident that the stop 39 not only constitutes means forlimiting the movement of the latch member 4L0, but its upper edgelikewise abuts against the under side of the toothed flange 20 and thusprevents the tooth 46 oi the latch member sliding transversely of theteeth 21 of the said Ill) toothed fiangeas might otherwise occur if itwere not for the provision of the said member 39. Likewise, thisengagement of the member 39 with the toot-her flange 20 serves toproperly position the binding posts 17 of the removable section 10 in aline with the binding or leaf retaining posts of the section 9.

In order that the rods 25 may be relatively braced between their endsand thus insure of proper engagement of the ends Z8 of the hooks 76 withone of said rods, a connecting link 81 is provided at its ends withopenings through which the rods extend and this link extendstransversely between the said rods, as clearly shown in Figure 1 of thedrawings.

It will be evident that when the temporary leaves 62 are arranged withineither or" the iixed binder sections, the leaf-retaining posts 47 willengage through the openings 48 in the said leaves and the posts 22 willengage through the openings 24, and at this time the openings 79 are notengaged by the hooks 76 and, therefore, no wear is imposed upon thewalls of said openings.

In the foregoing description and in the claims reference-is made topermanent leaves and temporary leaves and by permanent leaves is meantleaves which are to remain permanently in the binder as a whole and bytemporary leaves is meant leaves which are to be placed in the binderand employed only for a short time and then removed therefrom.Therefore, in the specific use to which the invention is intended to beput, the permanent leaves will be the text leaves of the Bible and whilethey may be trans posed from one of the permanent binder sections to theother, nevertheless-they are always retained within the binder. Thetemporary leaves are merely blank memorandum leaves upon which aminister will make not-es before delivering his sermon and which leavesare placed in the temporary binder section and retained in position forconvenient reference during the delivery of his sermon, after which theymay be removed and discarded.
